Ensuring that user inputs are __________ based on the expected data type is crucial in preventing SQL injection.
- Encrypted
- Sanitized
- Typed
- Validated
Ensuring that user inputs are typed, meaning they match the expected data type, is crucial in preventing SQL injection. This practice adds an additional layer of defense by ensuring that the input data is not only syntactically correct but also of the expected type.
When a CodeIgniter application's performance degrades, the primary debugging approach should focus on ______.
- Caching the entire application
- Identifying and optimizing queries
- Increasing server memory
- Upgrading CodeIgniter version
Performance degradation often relates to inefficient database queries. Identifying and optimizing these queries is a key step in improving the overall performance of a CodeIgniter application.
________ is a common protocol used alongside OAuth for secure authorization.
- HMAC (Hash-based Message Authentication Code)
- JWT (JSON Web Token)
- OpenID Connect
- SAML
OpenID Connect is a common protocol used alongside OAuth for secure authorization. It provides a way to verify the identity of the user and obtain additional user information during authentication.
For complex queries, Active Record Class allows method ________ to directly write parts of the SQL query.
- buildQuery()
- composeQuery()
- rawQuery()
- writeQuery()
The correct method for directly writing parts of the SQL query in Active Record Class is rawQuery(). This method is useful for handling complex queries where direct SQL is required.
How does CodeIgniter handle database versioning through migrations?
- A separate configuration file stores version numbers
- CodeIgniter doesn't support database versioning
- Each migration file includes a version number
- The database server manages versioning automatically
CodeIgniter handles database versioning through migrations by including a version number in each migration file. This version number helps CodeIgniter keep track of which migrations have been executed and ensures the database schema is up-to-date with the application's code.
What is the primary purpose of database migrations in web development?
- Data retrieval from the database
- Dynamic content rendering
- User authentication in CodeIgniter
- Version control of the database schema
Database Migrations in CodeIgniter are primarily used for version control of the database schema. They allow developers to manage and apply changes to the database structure over time, ensuring a smooth transition between different versions of an application.
In CodeIgniter, where should the controller files be placed within the application structure?
- /models
- /views
- /controllers
- /core
CodeIgniter follows the MVC (Model-View-Controller) pattern, and controller files should be placed in the "/controllers" directory within the application structure. The other options are not the standard location for controllers.
During high-traffic periods, a CodeIgniter application experiences slow session read/write operations. The likely bottleneck is ________.
- Database latency
- File system concurrency
- Network latency
- Server processing power
In a high-traffic scenario, the bottleneck for session read/write operations in CodeIgniter is often caused by file system concurrency. The file system struggles to manage simultaneous read/write requests, impacting performance.
What is the role of the 'system' directory in the CodeIgniter framework?
- It contains the core CodeIgniter system files
- It houses the application-specific configuration
- It is used for session management
- It stores user-specific data
The 'system' directory in CodeIgniter contains the core system files required for the framework to function. It includes the core libraries, helpers, and other essential components needed for the CodeIgniter application to run. Developers should avoid modifying files within this directory to ensure stability and compatibility.
What is the primary purpose of the Email Class in web development?
- Creating email accounts
- Handling email-related configurations
- Managing email templates
- Sending emails
The primary purpose of the Email Class in web development is to facilitate sending emails. It provides a convenient way to send emails, allowing developers to include various configurations and templates. This class streamlines the process of incorporating email functionality into web applications.
